Zoning
AP
Agricultural Preservation District
In addition to the general goals listed in the Purposes and Community Development Objectives section 103 of this Ordinance, the purposes of this Section are: To encourage and promote continued agricultural, open space, and conservation uses in the AP zoning district, while also permitting low density residential development as would be compatible with the existing rural character of the area and agricultural uses.; To recognize agriculture as a productive land use and as an ongoing and viable component of the economy of the township and Chester County and to provide suitable areas for such uses. To preserve prime agricultural soils that are currently in agricultural uses and to preserve natural resources, including Woodlands, Wetlands, and Floodplains, that are least appropriate for development.; To prevent adverse effects resulting from the encroachment and mixing of residential and other incompatible development with agricultural uses.; Accordingly, the district incorporates a density standard which, among other things: Provides for agricultural and low-density Dwelling uses; and; Facilitates the conservation of agricultural areas, Woodlands, Wetlands and Floodplains, surface and underground water supplies, and wildlife habitats, and the control of soil erosion due to surface water flooding.; In the AP Agricultural Preservation District, all provisions of this Article shall apply.
